Detailed Description

Contact mechanics calculations at element level (single contact pair)

Module hierarchy for contact analysis: Level 1 (Element): m_fstr_contact_element - Element calculations for one slave-master pair Level 2 (Assembly): m_fstr_contact_assembly - Processing all pairs in one tContact object Level 2 (Search): m_fstr_contact_search - Contact detection for all pairs in one tContact Level 3 (System): mContact - Managing all contact objects in the system

This module (Level 1) provides:

• Stiffness matrix and force vector computation for a single contact pair
• Tm/Tt matrix computation
• Friction state calculation

Module structure: m_fstr_contact_elem_common - Common utilities (Tm/Tt, friction state, etc.) m_fstr_contact_elem_slag - Slag method implementations m_fstr_contact_elem_alag - Alag method implementations m_fstr_contact_element - Unified interface (this module)
